Do you think criticizing without help is something valid?

I think that in situations where someone feels someone has done something wrong the best thing is to calm down and have a rational discussion rather then criticizing and having a scream fest.

no its never right it just as mean as hell shameon them

For some reasons, criticizing has been a part of human's lives. We tend to compare between apples and oranges and this is normal because we see the difference among all things. We by nature are innovative which drives us to make every things or situations better. Thus, we criticize if we see something wrong or out of the norm. Thing about it is, some people gets overboard of doing it and they don't consider the outcome of their criticism or how would the other person feels. In my opinion; no matter how much we opposed about how bad criticism is, we can never hide the fact that it's part of our lives that we need to deal with. It's either you take it positively or it may break you.

People criticize because they wanted you to act the way they act, think the way they think, and do the way they do... to support theirs.

This is really very bad

I do dislike criticize which has not aim to change, just for pleasure. I want help when I am in fault not to make me more sad.

No, it seems a bit pointless. Sometimes people criticising think that the other person should just 'get' what they are saying and change their faults but it is not always that easy and the person doing the criticising doesn't always know best anyway.
